Got this r31 silhouette flood car to rebuild.

Finally getting around to changing whole cold side.

(Look at that sludge)

lets see where this leads once it’s all together tomorrow.

..m'kay.... I see on my phone you're having difficulties interpreting the artfully hand drawn R31 wiring diagrams... you wouldn't credit it, but they're actually more accurate than those colour diagrams in gregory's and the like...

...for your purposes though, the wiring colour legend is on sheet 1....

....the fuel pump connector is top right on sheet 2....

...pin1 (black) goes to chassis ground -- pin5 (light green/red trace)...

The best way to navigate those drawings, is to open them up in whatever image manipulation/paint program you like, and use the straight line/ruler  tool (with a highlight colour) to trace along the wire lines...not hard, no rocket science involved...

Fun facts:

The OEM diagrams are drawn to top trim level spec ~ so for example, you're looking at Silo spec wiring, but the base S3 Executive trim is also covered by the same drawing (base models just don't have all the add-on luxury bits)

One of the more sublime bits of errata, is this bit...

The wire splice between pins7,14 doesn't exist (red) -- the bridge on the cluster PCB between the same pins (green) does exist...but it's not 'there' physically...it's actually more towards the center of the PCB, exactly at the spot where they tend to crack...and if it does, only half the dash lights work... can drive you nuts chasing it ; don't ; just solder in the missing splice...

These are 'intentional' soldered and taped splices inside the loom(s) ~ there's also unintentional splices like this, due to manufacturing process when a spool of one particular coloured wire runs out, and they splice in/on a new spool. Those splices above are in the loom, LHS, underneath the front guard panel (remove to get at loom)... if water's gotten into the looms, you can expect corrosion at these splices ... keep this stuff in mind, if in the future you get any weird electrical faults... 👍

Nice write up solder thank you. 
that problem had fallen into another days fun. I wanted to get this cold side in and turned over so it was wired up the same to get a start.

no luck I got a couple of cough’s before the battery died unfortunately.

we have some wether on the way and I’m back to work, I will order your plugs and re wire them in the near future. 🤙

[25RBGT]

As promised………… the first start. Rough and a few bugs to work out. Still she lives

[25RBGT]

Yeah I noticed this just now. No doubt she will be running smoother next start😂🤣😂

Similar to a video I watched on YT recently. They were like "that sounded really weird..." They took it one step further though. They forgot to put cylinder 1 spark plug back in after checking timing.
